Aquatic plant system of landscape lake

Abstract

The invention relates to the field of water environment pollution control, and provides an aquatic plant system of a landscape lake in order to solve the problem of insufficient pollutant control dueto persistent organic matters in the sediment. The aquatic plant system of the landscape lake includes aquatic plants planted in the landscape lake, the quantity of varieties of the aquatic plants istwo or more, the aquatic plants include at least one of dwarf cold-tolerant Vallisneria natans and Vallisneria spinulosa, and the total planting area of the dwarf cold-tolerant Vallisneria natans and Vallisneria spinulosa is not lower than 70% of the area of lake water. The dwarf cold-tolerant Vallisneria natans and Vallisneria spinulosa must be rooted, so the roots of the dwarf cold-tolerant Vallisneria natans and Vallisneria spinulosa must penetrate deep into the sediment, reduction of the content of ammonia, nitrogen and phosphorus in the sediment and reduction of internal pollution sources of the landscape lake are benefited, and the sediment is not prone to continuously release the pollution sources to the water of the landscape lake in order to make the self-purification ability and the self-repairing ability of the water stable, thereby the water control is thorough and complete.

Description

technical field [0001] The invention relates to the field of water environment pollution control, more specifically, it relates to a landscape lake aquatic plant system. Background technique [0002] Landscape lakes are generally artificial lakes, which are a kind of lake dug out by people in a planned and purposeful manner, and are produced in an unnatural environment. The landscape lake provides the city with a suitable landscape atmosphere and is conducive to improving the quality of the urban environment. [0003] As an open system, the landscape lake is easily polluted by the surrounding environment. At present, there are mainly two types of pollution prevention and control methods for landscape lake water bodies. One is to use ecological purification technology to build aquatic plant water purification systems to enhance the self-healing ability of water bodies by planting aquatic plants. The other is to use artificial circulation purification technology. The method ...

AI Technical Summary

Problems solved by technology

However, the fluidity of the landscape lake is poor, the water area is large, the bottom mud is thick, and the bottom mud contains a large amount of organic matter, and the internal pollution source is serious. However, the existing pollution prevention and control measures mainly purify the water body of the landscape lake, and the nutrients in the bottom mud The substances are still difficult to decompose, so that the nutrients in the sediment can easily affect the water quality of the landscape lake, and the pollution control is not thorough enough. Therefore, there is still room for improvement
